The Natural Bridge in Aruba was was a popular tourist destination until its collapse on September 2, 2005. It was on the north coast of this Caribbean island, which is in turn just off the Venezuelan coast. The bridge had a span of 98 feet, a height of 13 feet, a width of 50 feet, and a thickness of 8 feet. There are fossil coral heads (one of which is nearly four feet across!) embedded in the rock, revealing its corraline origin. There is another similar natural bridge still standing nearby with a span of 72 feet. Photo and measurements by Danny Horowitz.
